RAILRQAD-TIE.

Application filed June 15, 1914.

T 0 all whom it may concern lie it known that I, DANIEL W. THOMP- son, a citizen of the United States, resid in g at lVilmington, in the county of Clinton 3 and State of Ohio, have invented certain he and useful Improvements in Railroad 'lies, oii' which the following is a specification.

My invention relates to improvements in railroad ties and has for its primary object to provide a tie that simple as to construction and which will operate to support the rails in a reliable manner and also hold them against creeping or spreading.

in object oi importance is to provide a tie that is formed of similar sections that are oppositely disposed and reversely arranged and also united to provide the'tie, said secti one being formed in such manner that the rails are securely clamped upon the tie, each section carying integral rail clamping jaws or members.

Another object is to provide a device of the character described that is of simple construction, dispenses with the separate fastening means usually employed to secure rails upon the ties and which is inexpensive to manufacture and install, the sections be ing capable of shipment in large numbers irrespective of their relative arrangement when assembled.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out as claimed.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a. top plan view of my improved tie showing the same in assembled. position, Fig. 2 is a side elevation of the tie in assembled position with the rails removed, Fig. 3 is a transverse sectional view taken on line 33 of Fig. 2 showing the sections secured to each other, and Fig. 4- is an end elevation of the sections showing them in position prior to the uniting thereof.

Referring to the drawings by characters of reference, the numerals 1 and 2 designate as entireties longitudinal tie sections that are identical as to construction and desi nod to be secured in such manner that atie is Specification of Letters Patent.

provided and rails securely clamped and supported.

Ea ch tie section 1 and 2 consists of a. body 3 which is trapezoidal in cross section, to provide a horizontal base l and upwardly and inwardly inclined outer and inner sides 5 and 6 respectively. one oi? its ends each tie section is recessed to provide a rail seat 9, and an outer clamping jaw 0*. This jaw has a beveled rail base engaging face 10, which overh the rail seat 9. This beveled :lace terminates short of the seat to provide an outer shoulder l0 at the juncture of the face and seat. An inner shoulder 10" is formed at the opposite end of the seat. To permit the rail base to be placed upon the seat 9 beneath the beveled face 10, and in engagement with the shoulders 10 and 10 the adjacent end of the central portion 11 of the tie section is beveled as at 10. This beveled end terminates at a point above the seat to provide the shoulder 10. The seat and beveled face 10 are inclined downwardly in the direction of he outer side 5 of the tie sections. he other end of each tie section is reduced to provide a rail seat l0 and an inner clamping jaw 10. This jaw is provided with a beveled rail engaging face 10 which overlies the base 10 and terminates short of the base to provide an inner shoulder 10 This seat and beveled face are also inclined in the direction of the outer side 5 of the tie sections. The upper side of the outer portion of the end of the tie section is located in the plane of the seat 10 The tie sections are assembled to position the seat 9 of one section adjacent the seat 10 of the other section. After the tie sections are applied to the rails so that the inner clamping jaws 10 engage over the inner portions of the bases of the rails, and the outer clamping aws 9 engage over the outer portions of the bases of the rails, the tie sections are moved toward each other to bring the inner sides 6 in abutting relation, after which they are secured together by means of bolts 7 and nuts 8 which engage the tie sections below the rail seats and by the bolts 12 which engage the central portions of the tie sections above the rails seats. As the seats, and as the beveled faces of the clamping jaws incline downwardly in the direction of the outer sides of the tie sections, they are brought into full abutting and firm clamp ing engagement with the under and upper sides of the rail bases, respectively, when the tie sections are secured together. When the tie sections are secured together, the lower sides l of the tie sections are disposed in an upwardly and oppositely inclined direction providing a longitudinally extending central rib on the under sides of the tie which prevents the tie from moving longitudinally of the road bed. The shoulders 10 and 10 and 10 engage the rail bases and hold the rails against any lateral movement with relation to the tie.

in p notice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most eflicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as set forth.

What is claimed is 1. A rail tie comprising duplicate sections, each section having a horizontal base and upwardly and inwardly inclined outer and inner sides, and means securing the tie sections together with their inner sides in abutting relation, and their bases inclined upwardly in opposite directions, said inclined bases providing the tie on its under side with a longitudinally extending rib adapted to prevent the tie from moving longitudinally of the road bed.

2. A rail tie comprising duplicate sec tions, each section having ahorizontal base and upwardly and inwardly inclined outer inner shoulder at the juncture of the second seat and the last named beveled face, and means securing the tie sections together with their inner sides in abutting relation, and their bases inclined upwardly in opposite directions, said inclined bases providing the under side of the tie with a longitudinally extending rib adapted to prevent the tie from moving longitudinally of the road bed.

3. A rail tie comprising duplicate sections each having a horizontal base and upwardly and inwardly inclined sides, a rail seat at each end of each section, clamping jaws on each section provided with beveled faces overlying the seats, said seats and beveled faces inclining downwardly in the direction of the outer sides, and means securin the tie sections together with their inner sides in abutting relation, the securing of the sections together moving the rail seats and beveled faces into full abutting and firm clamping engagement with the bases of the rails.

In testimony whereof I aflix my signature in presence of two witnesses.
